Starting a cafe shop business in Montenegro

Hello Everyone!
I've always thought of having my own cafe shop business in Montenegro, I've visited the country 4 times and I absolutely loved it. I'm aware that the country heavily depends on tourism but I've also noticed that locals spend much time outside drinking coffee. I have so many unique ideas that will make the atmosphere at the place very cozy but  I am not sure if this is the best time to launch a business. I am willing to take the risk and im Wondering how much would it cost me to start such a business? I've been to many cities starting from Rozaje in the north up until Kotor. Even in the pooerer cities I've noticed that people have the tendency to spend time outside. I attend to start with something small that I built up during the years. Thank you so much for your help.
